After watching 88% of orgs hit by AI security incidents, I built what I wished existed: a simple scanner that checks prompts before they go live. No enterprise sales calls. Just $29/mo.

Hi Product Hunt! 👋 I'm YOSHITATSU, founder of PromptGuard.

I built this because OpenAI themselves said: "Prompt injection cannot be fully solved." — That means every AI app is exposed. Including yours.

PromptGuard adds a guard layer OUTSIDE the model:
✅ 1 line of code to integrate
✅ Detects prompt injection, PII leaks & jailbreak attempts
✅ Works with OpenAI, Anthropic, Gemini, Mistral
✅ Free tier available — no credit card

Happy to answer any questions!
